network packets that we parse and not against local users trying to gain root
access through ping's set-uid bit - this is handled by dropping privileges very

7703a6ff27 Add the -R option to allow fsck_ffs to restart itself when too many critical
errors have been detected in a particular run.

Clean up the global state variables so that a restart can happen correctly.

Separate the global variables in fsck_ffs and fsdb to their own file.  This
fixes header sharing with fscd.

Correctly initialize, static-ize, and remove global variables as needed in
dir.c.  This fixes a problem with lost+found directories that was causing
a segfault.

Correctly initialize, static-ize, and remove global variables as needed in
suj.c.

Initialize the suj globals before allocating the disk object, not after.
Also ensure that 'preen' mode doesn't conflict with 'restart' mode

ae3bc0acff Add an ability to stop gmirror and clear its metadata in one command.
This fixes the problem, when gmirror starts again just after stop.

The problem occurs when gmirror's component has geom label with equal size.
E.g. gpt and gptid have the same size as partition, diskid has the same
size as entire disk. When gmirror's geom has been destroyed, glabel
creates its providers and this initiate retaste.

Now "gmirror destroy" command is available. It destroys geom and also
erases gmirror's metadata.

Promoting the SIGINFO handler's log message from LOG_INFO to
	LOG_NOTICE, and promoting the "Processing event ..." message from
	LOG_DEBUG to LOG_INFO.  Setting the logfile to LOG_NOTICE with this
	change will have the same result as setting it to LOG_INFO without
	this change.  Setting it to LOG_INFO with this change will include
	the useful "Processing event ..." messages that were previously at
	LOG_DEBUG, without including useless messages like "Pushing table".

	The intent of this change is that one can log "Processing event ..."
	without logging "Pushing table" and related messages that are sent
	for every event.  The number of lines actually logged is reduced by
	about 75% by making this change and setting syslog to LOG_INFO vs
	setting syslog to LOG_DEBUG.

Increase the size of devd's client socket's send buffer from the
	default (8k) to 128k.  This prevents clients from getting
	POLLHUPped during event storms.  For example, during zpool creation,
	the kernel emits a resource.fs.zfs.statechange event for every vdev
	in the pool.  A 128k buffer is large enough to hold the statechange
	events for a pool with nearly 800 drives.

d685f88bee In remote_send_thread, if sending a request fails don't take the
request back from the receive queue -- it might already be processed
by remote_recv_thread, which lead to crashes like below:

  (primary) Unable to receive reply header: Connection reset by peer.
  (primary) Unable to send request (Connection reset by peer):
      WRITE(954662912, 131072).
  (primary) Disconnected from kopusha:7772.
  (primary) Increasing localcnt to 1.
  (primary) Assertion failed: (old > 0), function refcnt_release,
      file refcnt.h, line 62.

Taking the request back was not necessary (it would properly be
processed by the remote_recv_thread) and only complicated things.

5d69ed535e For memsync replication, hio_countdown is used not only as an
indication when a request can be moved to done queue, but also for
detecting the current state of memsync request.

This approach has problems, e.g. leaking a request if memsynk ack from
the secondary failed, or racy usage of write_complete, which should be
called only once per write request, but for memsync can be entered by
local_send_thread and ggate_send_thread simultaneously.

So the following approach is implemented instead:

1) Use hio_countdown only for counting components we waiting to
   complete, i.e. initially it is always 2 for any replication mode.

2) To distinguish between "memsync ack" and "memsync fin" responses
   from the secondary, add and use hio_memsyncacked field.

3) write_complete() in component threads is called only before
   releasing hio_countdown (i.e. before the hio may be returned to the
   done queue).

4) Add and use hio_writecount refcounter to detect when
   write_complete() can be called in memsync case.
